- APPARATUS EORT'REATING BARRELS. j

Specification of ,Letters Patent.

To all whom, it may concern:

Be it known that I, HARRYToiicinani, a citizen of the United States of Amerlca, residing at Chicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvement in Apparatus for Ea wall, 8, of heat-resisting and heat-insui lating material. Another pipe, 9, extending from a pump or blower, 10, serves for corn 'veying forced unheated air into the chain- Treating Barrels, of which the following is a specification.

This invention relates to an apparatus for treating barrels, and particularly to means for coating them with pitch. The old pitch in barrels usually is removed by burning out the barrels. This method has the disadvantage that a large volume of smoke is generated, which is obnoxious. and it is also dangerous on account of the inflammability of the pitch. Pitch for pitching barrels is mostly liquefied in ketties built into or associated with open flame furnaces. This method also involves a considerable risk on account of the inflammability of the material used.

An object of the present invention is to depitch barrels by forcing air of a suitable temperature into them, so as to melt the old pitch or burn it out, without an open flame and then to apply a new coat ofpitch.

Another object is to convey heated air through a kettle filled with pitch to liquefy the material without the use of a furnace.

Another object of the invention is to pro-. vide a method and means for heating air to a very high temperature, for reducing the temperature by increasing the volume of the air and for imparting a whirling movement to the air, to convey the same into the barrel or kettle.

Other objects will be more fully understood by reference to the following specification and the claims appended thereto, and by reference to the accompanying drawing. The latter shows by way of example, an apparatus for performingthe method which forms a subject matter of this invention.

In the d 'awing: Figure 1 is an elevation, partly in section of the apparatus. Fi 2 is a top plan view of the same.

The air is heated by means of a burner 1, to which the fuel in gaseous or liquid form may be sup-plied through pipe 2. The con struction of the burner itself does not form the subject matter of the invention; it is advisable, however, to use a burner generating a very hot, possibly sootless flame. The burner is disposed within a box or casing 4, provided with an opening 5, to

l pipe (3, with a mixing chamber 7, preferably of cylindrical shape.

which the air to be heated may be supplied by means of a blower 5 or such like. This box is in communication by means of Themixing or collecting chamber 7 has ber 7. The air flows through pipe 9 at a speed exceeding the velocity at which the air from casing 4: enters the chamber, and it therefore imparts to the heated air a rapid movement. Pipe 9 preferably is dis- .poscd in angular direction with respect to a radius drawn to the point where the pipe opens into the vallof chamber 7, in'iparting thereby a tangential whirling movement to the heated air. The chamber 7 has two outlets, from which the conduits 11 and 12 lead to the depitching device 13, and pitching device 14, respectively. The conduits or pipes 11 and 12 may be provided with suitable valves or dampers 20, to regulate the flow of the heatedair from the collecting chamber. The pipe 11 extends through the barrel seats 15, with which the injector nozzles 16 are associated; the latter branch ofl' preferal'ily in verticaldirection from the pipe 11 and project through apertures '17 in the barrel seats. Flues-18 lead tothe smoke. stack 19,from the interior of the barrel seats, and serve for carrying oil the obnoxious smoke and odors incidental to all operations where heated pitch is handled.

The pipe 12 is connected by means of coupling 21 with a pipe 22, shown in form of a coil and disposed within the pitch kettle 23. After being conveyed through the material, in the kettle the heated air is discharged through riser 24; into the atmosphere, or it may be conveyed to some other place to be utilized. The pitching device shown includes a barrel seat 25 in communication with a pump or tank 26 in the interior of the kettle.

28 indicates the lever of the pump or some other means having a check valve for forcing liquefied pitch from the kettle into the tank and from there into the nozzle 27 of the barrel seat. It is obvious, however, that other pitching devices may be used and reference may here be made to devices disclosed in the United States Patents (327781. of June 27, 1899, or 617,185, of January 3, ,1899.

From the kettle 23 a flue 29 leads to the stack 19, to carry off the smoke.

The method for pitching the barrels is about as follows: The air conveyed from the casing 4 into the chamber 7, is in most cases of too high a temperature for the purpose desired. By blowing air into the chamber through pipe 9, a draft is created in the chamber facilitating the inflow of the heated air, and the temperature of the air in the chamber is reduced to a suitable degree to melt pitch. At the same time the volume of the air is considerably increased and a rapid whirling motion is imparted to the same, so

. that the air from the chamber flows at high speed into the pipes 11 and 12. Then barrels are placed in the seats 15, so that the nozzles 16 project into the interior of the barrels the hot air forcibly injected through the nozzles will have the same effect as the open flame, heretofore utilized for removing the old coating of pitch. The danger of fire is avoided and the obnoxious odor and smoke eliminated. The latter are removed through 2 lines 18 and stack 19. x The barrel is then coated with new pitch by means of the pitching device 14. In the suction stroke of the pump liquid pitch is drawn intothe tank and in the" pressure stroke it is discharged therefrom through the nozzle 27, into the in-' terior of a barrel on the seat 25. Y
